PUSHER FOB FURNAGES.

Application filed may 18, 1921. Serial No. 470,877.

To ali whom t may concern.'

Be it known that, THOMAS V. Anus, late a citizen of the United States, deceased1 late of Pittsburg-h, in the county of Allegheny and State of, Pennsylvania, invented certain new and useful Improvements in Pushers for Furnaces, of which the following is a specification. y

The present invention relates to the nrt l0. of charging sheet and tinplate bars into furnaces, and is for use particularly in connection with a furnace hearth of certain construction and a method of hea-ting sheet and tinplate bars. invented by Thomas V. Allis, and covered by two patents issued to him as follows, to wit: pair heating;7 furnace hearth, dated August 6th, 1912 Number 1,034,858, and reissued December 14, 1915, Reissue Number 14,032, and method of heating sheet-bars, dated December 10, 1912, Number 1,046,933. The present Iinvention is a continuation in partand modifications of a charging machine shown in Pat-cnt No, 1,402,036, dated January 3rd, 1922. entitled Method of, and machine Jtor charging sheet and tinplate bars into furnaces, by the same inventor; Thomas V. Allis.

Reference is made to all the above patab ents for a fuller understanding and description of the present invention 1n connection with the art in which it is used. In the last named atent, a. fixed or stationary charging mac4 ine or, pusher is described in con nectiofir'with its use for chargingbars placed on a' stationary cnarginig` table in front of thecharging door of a urnace. The present type of pusher is a' modification o f sand pusher in the earlier application,- and 1t will 4o be noted that the machine described in the present application is preferably used without the intermediate charging table, the usher being placed directlyin front of the iiurnaco hearth to be charged with tinplate bars, and may be partially attached thereto. The bars to be charged are charged in a collection, nt every :forward movement of A the pusher head in the present inventlon,

and it is observed that the gang methodv of charging is a distinct advantage, as will be seen from the description in the last named patent. A

lin the accompanyingdrawings forming part of this specification I have shown an example of the physical embodiment of the l right of Figure 2.

Figure 1, is a plan View of the invention. F igure 2 is a side elevation of Figin'e' 1. 5" Figure 3 is an end elevation taken from the left of Figure 2.

Figure 6 is a. partial detail transverse cross section of the pusher head of my in# vcntion on line 6-6 of Figure 7.

. Figure 7' is a longitudinal vertical ysection of the end portion of the pusher head on line 7*? of Figure 6.

Figure 8 is a transverse sectional detail of Figure 1.

The present type of pusher comprises the following parts. The numeral 1 indicates a preferably'cast metal base plate which is W, secured to the ioor or foundation prefer'` ably of concrete 2, and said plate carries rigidly mounted thereon a pair of opposite hand or reversed in position upright snp ports 3, 4, which have their web plate por- E tions ribbed at 5, 5 etc. for stiiening purposes.` Also rigidly mounted on the base plate 1, is a, motor (i of suitable power to drive the pusher head which will be described hereinafter. The said motor 6 is coupled to a slowdown Worm-gearing 9,

asc

the latter also mounted' rigidly on the plate 1. ,It is evident that as the speed of the motor is comparatively high, and theA pusher head moves slowly, the speed of the m motor must be reduced by means of the worm-gearing 8, before its power can 'he used properly. The shaft Sl of thel worm? gearing 8 is' mounted on its opposte'endsin bearings 10, 10, which are in turn n'ioituts ed on the upright supports 3, i above de l scribed. On the ends of the shaft 9, are 11, 11, which `form the means of rivin the'cha-ins 12, 13, the latter passing over idler sprockets 14, 15 respectively.

- On the end iin:

ofthe pusher remote` from the base'platc 1, are a pair of standards, '16, A16 secured preferably to the door 2, the

lower extremities 1'?t of said standards he me has proven its worth in actual mill use,

` 1. In a pusher,

being of simple construction, positive in operation, easil altogether a very desirable s accessory.

I claim:

with few parts, operated, and eet and tin mill a pair of inclined ways mounted on a supporting means, a bar support table between the inclined ways a series of V-sha ed grooves formed in the ar support tab ez cut-swag' ortions at the lbases of said grooves, a sli a le lpusher head on the inclined ways, a series o V-shaped teeth on the pusher head ada ted to operate in the bar table grooves, an ower means for o ei'ating the pusher headp grooves.

2. A pusher provided with a pair of drive sprockets and a pai-r of inclined ways mounted on supports, a grooved bai' supportv table having cutfaway portions at the bases of the grooves, mounted between the inclined )va s, a pusher head slidably carried on the inc ined ways, and having teeth formed complementary to the said bar table grooves, an outstanding flange on each side of the pusher head, power transmission means connecting thel said drive sprockets with the pusher head flanges just mentioned, for the purpose of operating the pusher head along the aforesaid inclined ways.,`

3. A pusher lhaving a .hase plate adapted to support a,m,otor and a vWorin-gearing, la pair of `inclined ways and a power shaft mounted onsaid base plate, a drive sprocket on each end 'of the power shaft, a pair of idler s rockets on the inclined ways, a groove bar support table on the latter, 'a pusher head havin teeth adapted to slidabl operate inthe bar table grooves, a pair ofy drive chains each passing over a drive and an idler sprocket,I and secured to the pusher head, for the purpose of propelling the latter alongthe inclined ways.

4. In a pusher, a base plate adapted to teeth along the said' inclined ways,

.and engage the grooves support a motor and a. worm-gearing, a pair the inclined ways and having teeth adapted I to operate in the, bar table grooves, and means for actuating the .pusher head.

5. In a usher,- ports, a pair of recessed adjustable stan ards ada ted to receive the outer 1i of a furnace ore-p1ate, a air of incline ways each having one end t ereof carried pn one ,of the upright supports, and its opposite end carried on one of the recessed adjustable standards, a bar table mounted between' the d amil 8Ulo bl f superimpose on t e ar ta e or. ush`v a charge of bars into the furnace. p

6. In a pusher, a pair of inclined ways niunted on. supports, a bar table positioned between the inclined ways, and having the same angle of inclination as the latter, and a pusher head on the inclined ways adapted to reciprocate along the bar table and move a charge of hars therealong.

In a pusher, a unitary structure having il pair of inclined positioned between the latter, a pusherhead adapted to reciprocateof the bar table. In testimony whereof I allix my signature. HANNORA E. ALLIS, iidmia/strai Allie, Decenas Witnesses:
